-K'Ihis invention relates to the adaptation of automobile power plants for purposes other than originally intended. Its principal object is to provide a device for the operation 5 of a wood saw and power pulley directly from the pinion end of an automobile main drive shaft.

It is known that power take-ofi' devices for automobiles have heretofore been prom vided in which certain types have the disadvantage of requiring numerous connections 25 which is positive, certain and reliab-le in action, and whereby the engine may be used for sawing wood and for driving machinery such as used for pumping, concrete mixing, hoisting, churning, threshing grains, etc.

A further object of the invention is to provide a portable or stationary sawing device which eliminates the requirement of the conventional saw table, consisting of a saw mandrel, bearings, frame and belt.

In the present invention a saw is attached to the pinion end of an automobile main drive shaft having a bearing adjacent thereto, and a table for resting the material to be sawed is secured to the automobile frame, thereby 4 u dispensing with an extra saw machine.

A further object of the invention is to provide collars having key waysfor clamping a saw to a shaft in an assembly whichwill not loosen or tighten by the working action of the 4c saw, thereby preventing a disengagement of the saw from the shaft or the locking of the clamping nut in the event of the saw becoming jammed which may occur with the use of the old style clamping collars not provided 5o with a key.

Vith these and other objects in view which Vwill appear in the course ofthe subjoined description, the invention consists of the features of construction, combination and arrangement of parts, hereinafter described and claimed, reference being had to the accompanying drawings, in which Fig.V 1 is a side viewpof a Ford automobile l showing my invention `ready for use.` i

Fig. v2 is a view on line AA of Fig. l.. Fig; 3 is an enlarged'portion of 3 Fig. l showing more clearly the manner in which I accomplish my resul Tas PATENT- or ifrcigffv Fig. 4 is apulley design adaptable for use in driving auxiliary machinery.- It is understood that pulley 4 may be of a modified n suitable form, for instance, a sheave or sprocket wheel for the transmission of'po'we'r to ,auxiliary machinery. 1

Referring to drawing and figures in Fig. l, l indicates the side frame members of the automobile, 2 the main drive'shaft'innormalV position, and 3 the rear bearing portion of the drive shaft housing which is normally fastened to the main dierential housing 4 by means of cap bolts 5. Bytaking out the cap bolts 5 and removing the drive shaft pinion from the end of the drive shaft, the drive shaft 2 maybe swung upward about the universal joint 6V for the application thereto of the present attachment. f When it is desired to drive the automobile from place tohplace fthe'drive shaft 2 may be again'placed'inits original position. The drawings specifically show the use of the device in connection with a rotary saw and a table for the same. For anchoring the bearing housing 8 in its working position, as shown in solid lines inFig. 1,' an angle bar member 7 is interposed Vbetween the side members l, said bar member :of the automobile frame 1 being held in place-by -bolt clamps 8f The cap bolts 5 taken'out at the first operation arey replaced in the drive shaft bearing housing so that their'heads are vnearest the rear shaft end and their threaded ends extend forwardly from said housing to receive nuts.l This permits locking one end of each of two braces 9 withthe two upper nuts in the bolt circle as at :twin Fig. 2, while the two lower bolts and nuts of said bolt circle are locked to the vertical web of angle bar 7 as at I-I, and F. The opposite ends of the braces 9 are bolted to the vertical web of the angle bar 7 as at G and I-I thereby rigidly supporting the housing 3.

On the tapered end of the drive shaft 2 is placed a tight-fitting washer or collar 10 with akeywayto receive the .key on the shaft, the shoulder 11 fitting into a washer or collar 12 as shown, and a circular saw 13 being put in place between-the -washers 10 .and 12 as shown in Fig. 8. The washer 12 which is also provided with a keyway for the shaft key is then put on the shaft, after .whiclrthe nut 14 is applied to the threaded shaft end for pressing the-washerl() againstthe taper of shaft andlocking the sawbetween the .washers 10 and 12. This constitutes the mounting of the-saw ,13 ready ifor work.

Thetable 15 for the saw is formed of boards, as shown, securely fastenedito two stringers 16, said-stringere being fastenedto the `side members 1, as shown in Fig. 2^by means of angle brackets V17 (Fig. 1).

AWhen a pulley 18 '(.Figi isfto be mountand at vpoint AJ ed for use vin driving auxiliarymachines,

washers 10 and 12 are not used. The pulley Lhas 1anl axial l'taper bore 19 and Aa Vkeyway,

is placed onthe-taper end of drive shaft 2 and isthen locked securely with'the fnutlll.

From Ithe :foregoing description anddrawings it will Vbe apparent that ;I .have thus provided an extremely eiicient and inexpensive device that converts an automobile intoA a useful direct driven saw machine and -bysimply substitutingav pulley for the rsaw yan efficient .auxiliary power drive lis -provided.

`While I have shown and described the pre- @ferred embodiment of my invention, asap- .pliedtoa Ford automobile, it is of course to be understood'that ,the device may be -applied to other automobiles and that vI reserve.thefrightgtomalre` such changes in the form, construction and arrangement of parts automobile frame, a power communicating element on the pinion end of said drive shaft for other than vehicle-driving purposes, and

means for clamping said element to said` ingsai'd' drivefshaft'housing from the frame of the vehicle, and clamping collars keyed on the said extending end of said drive shaft.
